Here’s HAO’s take on the Distortion +/250 Preamp circuit. It uses LED clipping and features a Brilliance switch for normal, bright, and warm settings. A TL072 dual opamp is used, but on the original, only one side is used and the other is left unconnected. In this layout, I used the unused opamp for the voltage … Read more
It’s been a while but I saw this little one was missing, and as I own the pedal and like it, I think it’s a worthwhile addition. So thought I’d try to get back into the game even if it’s a bit diddy and embarrassing compared to what the other guys are posting :o) Info … Read more
Here’s another plexi-in-a-box pedal. Fairly simple in comparison to others. I’ve drawn 2 layouts for this one; one stock and one with an adjustable gain mod. The EQ switch is optional, as some who’ve built this circuit say it’s pretty lackluster. The original uses an MC4558CN, but just about any dual op-amp should suffice (try … Read more
Request. It’s probably worth considering using 2 independent 500K log pots and separating the boost and drive sides. It seems a little restrictive to have them as a dual pot rather than being able to set their gain individually and of course it may also be preferable to make the toggle a stomp so that … Read more
Manufacturers info about the original: The Rust Driver Distortion Pedal from Hao was designed to recreate the classic sound of a late 60’s Marshall Plexi running at full-bore grind. Its carefully selected components allow the Rust Driver to faithfully perform this function with any amplifier, at any volume level. The result is a commanding guitar … Read more
A few people built the Rust Drive using my original layout (and other layouts which used the same schematic) and thought that it didn’t sound quite like it should and saying that there was a lot of noise. Aegert at FSB got a new one and traced it himself, coming up with an updated schematic, … Read more
Update 27-02-2012 – I’m keeping these online so that all previous versions remain accessible, but I suggest anyone wanting to build this does so using the new updated layout which can be found here. and the later version with a 3 position tone switch
